(54) ELECTRONICS TESTER


(57) The invention provides a cartridge comprising a socket made of insulative material and having upper and lower sides, the upper side having a first formation for releasably holding a first electronic device, the socket having a first socket thermal opening formed from the lower side to the upper side through the socket; an interface connected to the socket to connect the first device to an electric tester; a chuck of a thermally conductive material; and a first thermal post attached to the chuck, the first thermal post being inserted into the first socket thermal opening, an end of the first thermal post being thermally connected to the first device, such that heat transfers primarily through the first thermal post as opposed to the insulative material of the socket between the chuck and the first electronic device.
